ABSTRACT

A non-transitory computer-readable storage medium, a method, and a system for receiving display capabilities of a secondary vehicular display, determining metadata to display based on the display capabilities of the secondary vehicular display, formatting the displayable metadata, and transmitting the displayable metadata to the secondary vehicular display. The metadata is determined by receiving a data set from producer, comparing the data set against the display capabilities, and formatting the resultant data from the comparing as metadata.

TECHNICAL FIELD

Embodiments described herein generally relate to vehicular instruments, and more specifically to electronic instrument clusters.

BACKGROUND ART

Over the past decade, user handheld device deployment such as the iPhone® have grown rapidly (IPHONE is a registered trademark of Apple Computer Inc. of Cupertino, Calif.). These devices provide a networked general purpose computing platform in a small energy efficient package. Because of this incredible functionality, developers have been able to leverage the functionality into useful intuitive applications that improve the user's quality of life. Handheld devices now have become ubiquitous devices that are central to their user's world.

Implementations of navigation applications like Apple Maps offer locational and navigational information to the handheld device user. The accuracy, functionality, and usability of navigation applications have made them some of the most used applications on handheld device platforms.

However, barriers and limitations to a very desired use case, automobile navigation, persist. Handheld devices have relatively small screens that are difficult to view while maintaining the wide field of view for driving. Device mounts are often cumbersome and intrusive. Operating a vehicle while interacting with a handheld device is dangerous and illegal in some jurisdictions.

Past attempts at resolving these problems have involved interfaces to connect to head units in automobiles. The interfaces involved using wireless connections to present audio and video generated by the handheld device. Often the head units would simply mirror the screen of the handheld device, so the user would have a larger hands free view of the navigation application. However, this approach still can lead to the driver removing his visual focus from what is occurring in front of the car, and placing it on the head unit.

SUMMARY OF THE INVENTION

A smart phone connects with instrument cluster display of a vehicle. The smart phone queries the instrument cluster display for manufacturer implemented capabilities including fonts and space for individual text fields. The smart phone receives map navigation data from navigation application, such as Apple Maps. Based on instrument cluster display capabilities, the smart phone packages metadata, including formatting information specific to the display on the instrument cluster, in order to indicate to the driver an upcoming navigation change. This includes formatting turn by turn navigations, distance until next turn, estimated time until next turn, and instructing them to load an appropriate graphic for the type of maneuver.

The location circuitry 150 may be coupled to the CPU 110 to provide navigation information to any application executing on the CPU 110.

In one or more embodiments, communication circuitry 115 may couple the electronic device 100 to remote services 135. The communication circuitry 115 may include but not be limited to network adapters, wired or wireless, implementing the physical layer and data link layer of the networking stack, including but not limited to IEEE 802.11, 802.3, LTE, and Bluetooth® (BLUETOOTH is a registered trademark of Bluetooth SIG, Inc), and Universal Serial Bus (USB). The communication circuitry 115 may implement any communication protocols necessary to interface the electronic device 100 with the remote services 135, including but not limited to transport control protocol/internet protocol (TCP/IP) and user datagram protocol (UDP).

The remote service 135 may provide cloud based services to the electronic device 100 via the communication circuitry 115. Generally, the remote services comprise remotely connected server computer systems providing data requested by the electronic device 100.

In some embodiments communicatively coupled to the electronic device 100 via the communication circuitry 115 is a vehicle instrument cluster 140. The vehicle instrument cluster 140 can include vehicular instrumentation including speedometer, odometer, tachometer, fuel gauge, engine temperature, and system warning indicators. Additionally, the vehicle instrument cluster 140 may include a display with varying levels of capabilities. The capabilities are set by the vehicle's manufacturer.

FIG. 2 is an illustration presenting a system processing metadata according to one embodiment. A vehicular dashboard 200 houses many instruments necessary for properly operating a vehicle. The dashboard 200 includes an instrument cluster 205 and a head unit 220.

The instrument cluster 205 may be situated just beneath the driver's focus during operation so that when the driver needs feedback from the vehicle, the instrument cluster 205 is in the optimal place for viewing without necessitating losing focus on the road in front of the vehicle. In one embodiment the instrument cluster 205 may include instruments such as a speedometer, odometer, tachometer, fuel gauge, engine temperature, and system warning indicators. In one embodiment, the instrument cluster 205 may also contain a secondary display 210, wherein the head unit 220 may be the primary display.

Also included in the dashboard 200 can be a head unit 220. In one embodiment, the head unit 220 can include a computer, a coupled display, and a touchscreen coupled to the computer. The head unit 220 may serve as a primary interface for ancillary functions of the automobile. Ancillary functions may include air conditioning control, music and volume selection, communication interface selection, and maintenance status information.

In another embodiment, the head unit 220 may incorporate feature support for connected handheld device interaction such as Apple CarPlay™ (CARPLAY is a trademark of Apple Computer Inc. of Cupertino, Calif.). The head unit 220, in this embodiment, becomes an extension of the handheld device providing user interactivity similar to that of the handheld device itself. In this embodiment, applications made for CARPLAY will project their graphical content to the head unit 220 and provide a user experience similar to that of the handheld device.

In one embodiment, the instrument cluster 205 may contain a secondary display 210. As shown, the secondary display 210 may be embedded in the center of the instrument cluster 205. Alternatively, the secondary display 210 may be located outside of the instrument cluster 205. One example of a secondary display 210 outside of the instrument cluster 205 include heads-up displays (HUDs). The secondary display 210 may be of varying capability. In one embodiment, the secondary display 210 may be only capable of displaying text. In another embodiment, the secondary display 210 may be capable of displaying graphics in addition to text. The secondary display 210 may have preprogrammed graphical icons. The graphical icons may include common navigation icons such as but not limited to right turn, left turn, stay straight, and U-turn.

In another embodiment, multiple secondary displays may be supported. Anything that can delivered to the instrument cluster 205 based secondary display may also be delivered to a HUD based secondary display either exclusively or in parallel. Either secondary display may display different information from one another and have different display capabilities. For example string field lengths to display the current road name may be different for each secondary display and the data will be formatted individually for each secondary display.

The secondary display 210 may be coupled to the handheld device 230. In one embodiment, the secondary display 210 contains communication circuitry to establish and maintain the communication link 215 independently. The communication link 215 may be established by common wireless communication protocols such as BLUETOOTH. Alternatively, the secondary display 210 may not have an independent communication link 215 and may be attached to the head unit 220, which forwards data destined to the secondary display 210 through a different physical link between the head unit 220 and the secondary display 210. Additionally, the secondary display 210 may be capable of displaying information related to maneuvers and junctions. Maneuvers may be indications to the user on the operation of the vehicle, while junctions may be points at which maneuvers are to be performed. For example, a maneuver may be a right hand turn, and the accompanying junction may be at Smith Street. The junction may have an inferred intersection parameter or explicit intersection parameter. An example of inferred intersection parameter may be the roadway the vehicle is currently on, where the junction takes place at the intersection of the inferred parameter and an explicit parameter. The explicit intersection parameter may include all intersection roadways. For example, an explicit intersection parameter for two roads may be “Jones Street at Smith Street.”

The head unit 220 may be connected to the handheld device 230. The communication link 225 between the head unit 220 and the handheld device 230 may be wireless, via an appropriate protocol such as BLUETOOTH, or wired through an appropriate wired interface, such as a Lightning® cable (LIGHTNING is a registered trademark of Apple Computer Inc. of Cupertino, Calif.). The connection method for either communication link 215, 225, wired or wireless, is not to be construed as limited to the examples set forth, as they are just used for description.

FIG. 3 is an activity diagram 300 displaying the relationships between system components according to another embodiment. The system components include a vehicle 305 which includes a head unit capable of connecting to a mobile device 310 and a secondary display with some functionality for displaying an image. The mobile device 310 may be a cellular phone, a laptop, a tablet, or any other electronic device capable of connecting to the head unit of the vehicle 305.

The user 315 makes a request to connect 320 the mobile device 310 to the vehicle 305. The request may be made through a navigation application operable to interface with the head unit.

The mobile device 310 responsive to the user request to connect 320, attempts to connect 325 with the vehicle 305. If the connect request is honored, the vehicle 305 establishes connection with the mobile device 310. The connect request may be implemented utilizing BLUETOOTH, USB, WiFi, or any other communication technology suitable to support the coupling of the mobile device 310 and the head unit of the vehicle 305. Apple's iAP, built on the BLUETOOTH stack, is an example of an interface that will allow the connection, transmission, and reception of data.

The vehicle 305 provides capabilities 330 to mobile device 310. The capabilities may include that each display of the vehicle 305 may display navigation metadata, including how many characters can be displayed for each field of data that is supported and how many maneuvers it can store. For example, messages including fields that correspond to capabilities may be included in the capabilities 330. The fields may include unique identifiers or names. The fields may also include second display specific data including the maximum current road name length, maximum destination road name length, maximum after maneuver road name length, maximum maneuver description length, and maximum guidance maneuver storage capacity. All the fields would provide input to the mobile device 310 to describe the capabilities of the secondary display.

The mobile device 310 stores the capability information 335. The user 315 may request a set destination 340 on the mobile device 310. The request may be received as input from a navigational application.

Upon receiving request to set a destination, the mobile device 310 may examine the destination. Accordingly, the mobile device 310, compares the destination information, including maneuvers to the stored capabilities 335. The mobile device 310 determines the extent to which the vehicle 305 through the secondary display can display the maneuver data.

The mobile device 310 may send the vehicle 305 maneuver metadata 350 strings appropriate for the field size reported on connection, including detailed description of each navigable junction as well as flags to show “secondary” instruction where necessary. Secondary instructions may include multiple instructions or maneuvers to be performed in relatively short succession. If the vehicle 305 is capable of displaying secondary instructions, it provides the user 315 with a visual cue that another maneuver is imminent. The message sent to the vehicle 305 including the metadata may be a navigation route guidance update, which may include fields for states, current road names, the destination name, estimated time of arrival, time remaining to destination, distance remaining, distance remaining to the next maneuver, a list of current maneuvers, and a maneuver count. The states may include route guidance states such as, not active, active/guiding, arrived, loading, locating, and rerouting. The states may also include maneuver states which indicate the state during a maneuver which may include continue, initial, prepare and execute.

The mobile device 310 may also send navigation route guidance maneuver info update messages. These messages may include fields like the maneuver description, maneuver type, the after—maneuver road name, and junction type. The maneuver type field may be an enumerated type which defines common driving maneuvers including left turn, right turn, straight, U-turn, off ramp, on ramp, keep left, and keep right. The maneuver type is not intended to be limited to maneuvers listed here, but instead is intended to correspond to any maneuvers necessary to complete the navigation. The maneuver types may also be associated with stored graphics in the secondary display of the vehicle 305, so that upon the receipt of a maneuver type, the secondary display updates to include the stored graphic for that maneuver. The vehicle 305 updates the display 355 based on the received metadata 350.

In some embodiments, it may be necessary for the vehicle 305 to synchronize with the mobile device 310. As some metadata may be time sensitive, the vehicle 305 needs to update the mobile device 310 with synchronization data 340, 370 so that the timing between the vehicle 305 and mobile device 310 is consistent. This may be important, for example. When navigation updates require quick updates.

FIG. 4 is a flowchart processing display capability information to generate metadata according to one embodiment. At block 405, the metadata creation operation 400 receives the display capability information regarding the secondary display 210. In some embodiments, the display capability information may be included in storage local to the secondary display 210, including but not limited to firmware. Display capabilities may include the number of pixels available to an application, fonts, and text characters.

At block 410, the metadata creation operation 400 receives data to be displayed. The data to be displayed may come from a data producer executing on a handheld device. Not all of the data received may be displayed based on the display capability information. The data producer may be any hardware, software, or firmware that provides data that may be formatted for the presentation on the secondary display 210 of a vehicle. The data producer may be data from a navigation application such as Apple Maps, or it may be a news application sending a news alert, or it may be a weather application sending a weather notification. Data may be received through inter-process communication (IPC) implemented through shared memory, message queues, pipes or sockets.

At block 415, the metadata creation operation 400 determines metadata based on the display capability information. The received display capability information may be programmatically parsed into atomic elements pertaining to each feature element. For example, a single text element, possibly pertaining to the current road name, maybe extracted from the display capability information, and stored as a separate object. The object may have defined fields, pertaining to the available text characters available to be displayed. Additional fields may include enumerations for maneuvers, descriptions of the object, and information on how the object may be formatted as input to the secondary display 210. Each atomic element may then be organized into a data structure for retrieval, comparison, and reformatting. The data structure may be any structure capable of holding objects and being traversed by a process (e.g., an executing software entity) that presents the API's 310 functionality as described herein, including but not limited to linked lists, arrays, and trees. Once the display capability has been received, parsed and organized, the metadata may be determined prior to being transmitted back to the secondary display 210.

At decision point 420, a decision may be made based on whether the metadata is compatible with the display capabilities as described by the display capability information. This may include comparing string size availability for maneuver detail information, the number of maneuvers available, units of measure available, and relevant graphical display ability associated with a maneuver. If the display capability meets the requirements of the metadata, the decision tree proceeds to block 425. However, if the display capability does not meet the requirements of the metadata, further processing may be necessary.

At block 422, the metadata creation operation 400 may format the metadata based on the display capability information. The metadata creation operation 400 may format the metadata in a way understood by the secondary display. In one embodiment, the formatting information may be parsed out of the display capability information. For example, any extracted atomic element from the display capability information, may include details on how to format the metadata. This may include object fields indicating text information, graphic information, and positioning information. In another embodiment, the formatting information may be specified by an external, well known standard. A well-known standard may be published by the original equipment manufacturer of either the vehicle or the secondary display 210 itself in how to format communication messages operable to be understood by the secondary display 210. By utilizing either the formatting information or the standards-based formatting, the metadata may be displayed in accordance with the display capabilities. For example, either approach may yield truncated strings when the metadata includes more characters than the display may allow. Another approach may include an intelligent application of string shortening, where redundant characters that a human would infer, may be removed.

At block 425, the metadata creation operation 400 may send the metadata to the vehicle. The metadata may be packaged in a properly formatted message header for the underlying transport protocol. At block 430, the secondary display is updated to reflect the transmitted metadata, including any characters packaged at block 422, as well as the secondary display's interpretation of maneuver instructions. For example, if a maneuver instruction includes a graphic enumeration pertaining to a “turn right” command with a value of 2, the secondary display will interpret that enumeration to display a graphic corresponding to “turn right.” Additionally, if there is no internal graphic corresponding to a maneuver, the secondary display may display a default graphic or nothing at all.

FIG. 5 is a flowchart showing an illustrative comparison operation 500 generating metadata from a data producer according to one embodiment. The comparison operation 500 corresponds to one embodiment of block 410 and 415.

At block 515, the comparison operation 500 may compare the received data against the display capability information. The data received at block 510 may be deconstructed into atomic elements, or alternatively may be received in atomic form. The API 310 determines the form of the data. The data atomic elements may then be stored in a data structure for simpler manipulation.

The data structure containing the data atomic elements may then be compared against the data structure containing display capability information atomic elements. If there is a match in that a data atomic element meets the requirements of a display capability information atomic elements, then the data atomic element may fulfill the comparison.

The elements that fulfill the comparison may be placed into a separate data structure to be used to generate the metadata. Alternatively, the data atomic elements may just be flagged as successful comparisons and not placed into a separate data structure.

At block 520, the comparison operation 500 may generate metadata based on the data, display capability information and the comparison. The separate data structure may then be traversed. As the data structure is traversed, each traversed data atomic element may reference the corresponding display capability information element, so that the proper format for the secondary display 210 may be determined.
